Abstract: Disclosed is a liveness test method and liveness test apparatus. The liveness test method includes determining a presence of a subject using a radar sensor, performing a first liveness test on the subject based on radar data obtained by the radar sensor, in response to the subject being present, acquiring image data of the subject using an image sensor, in response to a result of the first liveness test satisfying a first condition, and performing a second liveness test on the subject based on the image data.

Abstract: A method of increasing a resolution of radar data is provided. The method of training a radar resolution increase model comprises generating a high-resolution training ground truth and a low-resolution training input from original raw radar data based on information corresponding to at least one of dimensions defining the original raw radar data, and training the resolution increase model based on the high-resolution training ground truth and the low-resolution training input. A radar data processing device generates high-resolution output data from low-resolution input data based on a trained resolution increase model.
